Abstract

                                The study conducted in Trichur district in Kerala in 1981-82, showed that the cost of cultivation per hectare worked out to Rs. 3668.42 in the case of high yielding .varieties and Rs. 3403.12 in the case of local varieties. The most important contribu- ting factor to the cost of cultivation was found to be human labour to an extent of 29.05 percent in the case of high yielding varieties and 40.49 percent in the case of local varieties. A comparison with the cost of cultivation studies during the years 1978-79 and 1979-80 showed an increasing trend, This can be attributed to the increased use of fertilizers and higher wage rates. The benefit cost ratios for high yielding and local varieties were 1.76 and 1.61 respectively. The cost of production per quin- tai of paddy worked out to Rs. 67.78 and 77.44 for high yielding and local varie- ties respectively.
